Sergei Gonchar has a dislocated shoulder and is out indefinitely.
That hurts a whole lot. Fortunately, the Pens had a plethora of NHL defensemen on the roster prior to Whitney and Gonchar getting hurt. The quality may not be the same, but the team will certainly get to fill out the roster.
Looking on the bright side, we'll get to see the young guys take a much larger role. I'm especially intersted to see how Kris Letang steps up after a year in the NHL. Maybe Golisoski can pull a Letang and make a case to be a full time member of the defense corps.
